Dan, you should know that VO2 max is highly overrated as a measure of
fitness.  For instance, Leonard Harvey Nitz, four time olympian cyclist,
with two olympic medals (1984), two world championship medals and over
17 national championships had a VO2 max of around 60.  His ergometer
scores were so bad that many of the women at the Olympic Training Center
scored better than him.  George Mount who placed 6th in the 1976 Olympic
road race had a similar VO2 max.  My VO2 max has been measured at 80 and
I've never been anywhere near an olympic team.  Yet by a pure VO2 max
measurement I'm fitter than them?  Maybe I'll go over to Harvey's house
and demand that he give me his medals when I show him my VO2 score. :)

Now VO2 max may mean quite a bit when we're talking about deep diving.
I'd image (though I don't know) that having excellent gas exchange can
only help in these types of dives.  But it has little corelation with
actual athletic performance.
